Abstract: It has been known for at least two decades that, in certain regimes, magnetically confined plasmas such as those within a tokamak or stellarator, may exhibit complex, non-diffusive radial transport that is badly modelled by means of traditional, effective, eddy diffusivities or conductivities. These regimes may become very important in next-step experiments, such as the ITER tokamak currently under construction in Southern France. In this talk, we will discuss some of the reasons for the appearance of complex transport behaviour in these plasmas, their implications for plasma confinement as well as give some hints about how these kind of regimes can be more properly modelled by using fractional transport theory. Comparisons with numerical simulations and, when available, experiments, will be also discussed.

The language of the workshop will be English and it will be open to all.
The programme will consist of three plenary talks:
– Alberto Loarte (ITER Organization) Modelling needs to support the ITER Research Plan and role of HPC
– Susana Clement (Fusion for Energy) Role of HPC in Broader Approach Activities in Fusion
– Xavier Litaudon (EUROfusion) EUROfusion E-TASC Programme and HPC role within it.
Invited talks and contributed orals. The abstract submission for invited talks and contributed orals is open now and will close on September 15th.
Selected presentations will be invited, by mutual agreement, to submit a journal paper after the workshop to a special issue published in Plasma Physics and Controlled Fusion (@IOPPublishing).

Coupling plasma and wall currents for disruption simulations
Speaker: Dr. Francisco Javier Artola Such
When: 24-Jul-2020 at 18:00 (CET, Prague).
Abstract: The talk will be about disruptions events that can arise in tokamaks producing large heat and electromagnetic loads on the structures surrounding the plasma. The dynamics of these events are complex and 3D simulations are required to understand present experiments and to assist the design and operation of future machines. Disruptions induce wall currents which in turn determine the plasma motion, therefore it is necessary to couple these currents to the plasma in a self-consistent form. In the presentation different methods for such a coupling are explained for 3D MHD codes and examples of 3D MHD simulations of Vertical Displacement Events (VDEs) are also presented.
